2.3.1.2.1 Setting up the serial port
☞ You can send AT text commands to NINA-B3 to execute tasks using open-source terminal
emulator software that supports XMODEM like TeraTerm or ExtraPuTTy. Alternatively, you can
send all AT commands described in this section using the s-center software in AT mode. See also
the s-center user guide [6].
Procedure
The examples in this procedure have been created and tested on EVK-NINA-B31 using TeraTerm.
1. Connect the supplied serial cable from the J8 connector on EVK-NINA-B3 to the USB port your
computer. For further information about setting up EVK-NINA-B3, see also EVK-NINA-B3 user
guide [3].
2. Download and unzip the latest u-connectXpress software from u-blox Product Resources.
3. Discover the COM port number for the USB Serial Port on your computer (MS Windows:
Start>Device Manager>Ports). See also “Setting up the evaluation board” in the EVK-NINA-B3
user guide [3].
4. Start your chosen terminal emulator and open the connection to the USB serial port (COMx).
